don’t count your owls before they are delivered*
Those night owl logos are starting to appear on parts of the Tube, ahead of the opening of the all-night service.
The design is quite clever, modernising the old night bus owl logo and even working in the dot from the lower case "i" from TfL's preferred typeface.
There's a great TfL style guide which describes their entire signage design in around 200 pages, for anyone THAT keen.
I can't help also noticing the Seoul night bus symbol, which somehow seems to be a step on the route.
And now I'm wondering whether they will put one on platform 9 3/4 at Kings Cross?

shiny happy crunchy building
I've had plenty of office moves over the years including every form of floor repacking, and experienced many of the ergonomic trends to get more people into the available space.
Yes, I've had those boinging seats, the relaxation swing area, the beach scene, the special hoteling pedestals and even the electric height-adjustable desking favoured by certain Scandinavian countries.
I've also probably been in more temporary offices than proper permanent ones, as a by-product of corporate lifestyle where whatever office space is found isn't quite enough and then another building nearby has to be leased for the over-spill.
I'm finding a current situation slightly amusing, where the building I was in yesterday was built as overspill for another building nearby. In order to do it, the previous building on the space had to be demolished. The construction crews brought in every form of Tonka Toy imaginable and that included a Rock Monster building eater.
Simply put, you could point the big yellow machine at a building and it would somehow ingest it whole and spit out rock pebbles at the back. Before the current building was constructed, we'd look out of the windows of the one nearby and watch the Rock Monster at work. It's not every day you see a whole headquarters building gobbled to dust.
Or is it?
I was in the shiny-shiny replacement building this week and when I looked out of the window I could see the old building. When I say old, it was late 20th Century.
Guess what?
The bright yellow Extec C12+ was at work crunching its way through that very building. I could marvel at the 350-hp Caterpillar C-9 industrial diesel engine and the large vibrating feeder with grizzly and separate discharge conveyor for fine rock. Now I was in the new building watching my old vantage point destroyed before a new even shinier building would take form.
And the overspill of people from the current building? They are over the road in yet another temporary building.
Time for that Queen song maybe?
"And another one, and another one, and another one bites the dust."

all watched over by machines of loving grace (rebooted)
One of the side-effects of the kitchen replacement is the shock testing we've given to the various electrical circuits in the house.
The electricians had to test the 30 amp and earth leakage trips (sounds like a space movie?) in order to issue a new certificate. It meant having the power turned on and off about 10 times, sometimes in quick succession.
We've an ever-increasing number of connected devices here - along the lines of the internet of things/thingyverse - so it was a good test of general robustness.
I'd already switched off the servers, but realised the house nowadays has myriad home automation devices. I wondered if they would all survive and restart or whether it would be like the olden days with VHS recorders, where everyone eventually had them with the flashing clock because it was too much trouble to re-programme.
In practice everything seems to work.
The wifi, the BT broadband router, and the various computers all regained their links to the internet.
The home automation hubs for the hue lights, harmony media control, nest heating and smoke detectors also seem to have resynchronised. I'd previously mused about whether a 'home reset' would be troublesome, but so far everything seems to have figured out how to restart gracefully.
As Richard Brautigan said:
I like to think
(right now, please!)
of a cybernetic forest
filled with pines and electronics
where deer stroll peacefully
past computers
as if they were flowers
with spinning blossoms.

almost time to reboot the kitchen
Now we are on the last leg of the kitchen refit, it's time to take a peep at the manuals. There seems to be more than, say, with an Aga. The user guide for the oven came with a huge set of software licences, similar to the kind of things you get when installing Windows.
It seems to include software from Texas Instruments, jpeg, The Wide Project, Kronos EGL, Open GL ES, Freetype, ucdn, GIF Workspace, Harfbuzz and Imagination Technology GPU drivers. The copyrights include references to Codethink, Google, Red Hat, MIT, World Wide Web Consortium and even SGI.
What could possibly go wrong?

taking the biscuit
A slight diversion today, into the world of biscuits.
We've had a few tradespeople around over the last couple of weeks, and as well as coffee and tea, there's been a need for an ample biscuit supply.
That includes the currently half price choccy selection from Marks, which is an easy crowd pleaser. They are mainly traditional biscuit types and disappear at a great rate.
Co-incidentally, this week Time Out has just done a survey of the top 27 retro biscuits, ranked worst to best and I couldn't help but take a Peak Freans at the result.
No great surprise or spoiler that the fig roll was bottom at 27.
Shockers further up the chart though, with one of my favourites languishing at around number 19.
That's the Chocolate Bourbon, which should, by rights be in at least the top 10 and probably the top 5. Even the Hobnob proved controversial and garnered a surprise ranking.
I won't spoil the rest by describing Time-Out's so-called winner, but let's just say that anything that needs an animated furry padger or banda or whatever it is to advertise should automatically be disqualified.

white engine or black engine TDi?
Driving along the motorway today I noticed several commonplace situations. High powered sports cars with one occupant. Outside lane speeders. Tailgaters using their brakes to keep a minimum distance. Cars parked in jams in the cone sections with the engine left running. Plenty of easy ways to create higher emissions.
Later I found the definition for the UK emissions test, devised in 1970 and last updated in 1997. It uses the Urban, Extra-Urban and Combined tests. The Urban is self explanatory, simulating stop-start driving from cold in a built-up area. Extra Urban is actually about driving at speeds averaging 39mph and up to 75mph in a non-urban environment. The Combined is simply the addition of the two tests. I was interested to see how many miles of variation were covered.
Any guesses? 10 miles urban and 30 miles non-urban? Maybe a combined varied total of, say, 40-50 miles?
Oh no.
Urban is 2.5 miles. Non-Urban is 4.3 miles. Combined is therefore 6.8 miles.
They do repeat the tests multiple times, but it is still a very simple and predictable formula.
I decided to have a pry into the world of car testing. There seem to be several basic ploys:
1) Thin, low rolling resistance over-inflated tyres.
2) Changing the wheel geometry to optimise it for the test conditions.
3) Changing the car lubricants to low resistance variants that don't need to be warmed.
4) Adjusting the engine management software to optimise the test *cough*
5) Disconnecting the alternator, which otherwise sucks power.
6) Switching off all the ancillary systems like air-conditioning, heating and similar.
7) Removing passenger wing mirror and taping over car body gaps to reduce drag.
8) Using the agreed ability to reduce the findings by 4% to cover experimental inaccuracies.
There's more, but this is enough to get an idea of how the test results will start to veer 20%-30% away from the figures stated in advertisements and brochures.
The above situation isn't the basis of the current emission testing claims, but is possibly another example of how a whole industry routinely deploys ruses to achieve the best results in their marketing outputs. No-one has cared that much about the exaggerated claims.
A quick example is the popular Ford Fiesta, which I arbitrarily selected to check the numbers. Autocar's review said "all 1.0-litre Fiestas apparently do 65.7mpg...expect something in the mid 40s from the turbos and early 50s for the non turbo." Parkers review of the 1.0L Fiesta said "...claimed to average 65.7mpg. Driven normally it'll probably return between 40mpg and 50mpg." Okay, these are respectably high figures, but still less than the 'apparently/claimed' figures.
So now we get the outrage about Volkswagen leaving a test detection mode enabled in the Bosch supplied engine management systems. I love that the press talk about a special defeat device as if it is another piece of hardware.
My simple view is it depends whether it's a white engine or a black engine.
The 'white' 2.0L TDI was an older design without a selective catalytic reduction (SCR) system. An SCR squirts atomised urea into the exhaust to cause the nitrous oxide to break down, creating lower emissions. The white engine was about to be replaced with the black engine which one includes an AdBlue system to do the NOX reduction.
Maybe the naughty engine management software was originally intended for the bridging period between the older white engine and the newer black one?
It's fascinating now that cars are more or less computers on wheels or X-by-wire as the trade calls it. One of my prior cars had the then new technology of brake by wire, also supplied by Bosch. It self-reported an error at a certain point and I took it to the man at the service department.
"Ahah," he said. "That'll be the Sensotronic brake system, one thousand guineas please, sir..." He winked.
It turns out that the software counted braking actuations and was designed to report itself after a certain number. Fortunately it also transpired that the car manufacturer abandoned the system and recalled all the vehicles that used it. The service guy's wink indicated that I could have the whole system replaced under warranty (just before I sold the car). I shall watch for the re-emergence of this type of system (iBooster anybody?) in electric and hybrid cars over the coming years.
So in the current situation Volkswagen did something wrong. The lawyers and 'traders' will make sure that they take a huge dive. I suppose there will be class actions as more lawyers sniff the polluted air. But there's also a kind of hypocrisy as many folk still aspire to gas guzzlers.
The immensely popular Ford F150 truck in the USA only manages around 16-17mpg and splutters out 407g per mile of CO2. That's about 4 times the CO2 of the aforementioned Fiesta, or more than double the emission of a Ford Transit van. Curiously the NOX emissions don't feature on the general marketing blurb, while the 0-60mph, mpg and CO2 do.
I still wonder how many people even know their car's CO2 level?
Yet we are now all hearing about the NOX emissions in the VW saga, which will presumably kill the tiny US market for all types of diesel car for the foreseeable future.
To my surprise, that F-150 monster is still petrol (gasoline) only. With a rumoured first ever diesel version perhaps slated for 2018.
But that was before the scandal.

Blood supermoon eclipse
I took a mid-evening snap of the moon on Sunday, thinking I might have a peep at the blood moon eclipse at around 3.15am on Monday morning.
I somehow woke at 2.45am and decided to take a look at what was happening. Would there be a clear sky? Would I be able to see anything?
Although the moon had moved to a completely different part of the sky, I could see the unfolding of the supermoon eclipse. First the arc created from the shadow of the earth, creating the white to black curve across the bottom of the moon which gradually decreased in size.
Then, as the shadow completely covered the moon, the white light gave way to the red light creeping around the edges of the earth and showing that -oh yes- the complete moon was really still there and highly visible.
My drowsy snapshots were taken on the weird camera I constructed the other day from the Nikon lens on the little OM-D EM-10 body with 8 second exposures.

restoring power to the kitchen

quick video test of a Nikon 300mm zoom on an Olympus OM-D EM10
I've had to suspend the video camera rig experiment for a few days whilst the kitchen work proceeds. I did get my hands on a new lens converter though and I've taken it for a very short spin.
It's a simple converter from Nikon format lenses to micro 4/3 and cost the princely sum of £10.99.
It's amazing.
I've only had a few minutes to try it, but I can already tell it shows great promise. The knurled silver ring can be twisted to adjust the aperture, even on Nikon 'G' lenses.
I took my most modest Olympus EM10 (which has the least sophisticated stabilisation) and added the biggest Nikon lens I could find (a 70-300mm zoom). On a micro 4/3 format this is the equivalent of 600mm at the zoomed out end.
Then I tried a few hand held zoom and focus tests through a window. There were plenty of little glitches, like focusing manually in an impromptu situation and keeping the whole camera steady and framed. Of course I failed on most of these points (!), but I'll regard this as a 'before' test which I'll aim to recreate with the adapter and lens stabilised on the camera rig.
It might be another week or more before I have time to do that however. Today it's all about reconnecting the rest of the household electricity. I may have to power down the wi-fi for a while.

this time it is a surfeit of cardboard and polystyrene
All that empty kitchen space has been refilled with boxes and packaging, until we can get the new kitchen unpacked and installed. There's a few bits missing, notably the washing machine and the ovens.
Meanwhile, it's time to get the other items arranges in a tidy line around the walls.
There's a new hole to cut in the floor too, to add another pipe to connect the water softener, which will need to go in a cupboard instead of under the sink.
My black bobble hat has acquired a new white spotty colour scheme from putting the mist coat onto the ceiling. That's the preliminary coat of watered down paint which gets sucked into the fresh ceiling plaster.
I know, it's all looking a bit messy still, but will start to come together when I dab some undercoat onto the walls to hide the multiple archaeological layers of paint-schemes.
Then for the fun part as we start unpacking everything.

a simplified algorithm for car test emission reduction (YMMV)
Since the days of this lovely VW Karmann Ghia, there's been set of statistics produced by car manufacturers about the expected performance from their cars.
The car featured above could accelerate from 0-60 in around 27 seconds, which was at least 3 seconds faster than the regular Volkswagen Beetle and it could get around 30 miles per gallon, although in those days the adverts didn't include performance small print.
Based on my own current car's live readouts, I get about 45 mpg average, yet the description in recent magazine advert small-print shows 53.3 for the combined mpg and up to 67 mpg for the extra-urban. Parker's car guide shows 46 mpg as their estimate, which is very close to my own.
No-one really believes the bigger numbers in the car adverts, and I usually look for the smallest number as the one most likely to be true. In the case of my car its 'urban' which shows 44.8 mpg - close enough to my own estimated 45 mpg - which rises to 50-53mpg on a really long motorway run. I've never seen 60, let alone 67 mpg.
And I don't think I'm a heavy footed driver, I hardly ever engage the 'Sport' mode and will often use the triple radar-assisted intelligent driving mode "Distronic Plus" where the car makes its own decisions about speed.
So there's a general situation which I will refer to as "Your mileage may vary" which is so commonplace it even has its own short form as YMMV.
For example, the American EPA/DOT has a whole screed of small print about YMMV on its printouts.
The 'Golden Vehicles' used for the tests are probably put on thin tyres to lower rolling resistance and presumably tweaked for ideal conditions in what amounts to a wind-resistance free environment.
I notice that a few cars such as some Mini Coopers, the Ford C Max Energi, Lincoln MKZ as well as some Hyundai and Kia cars have all reduced their mpg claims after being randomly tested in the USA.
That brings us to the recent kerfuffle over the diesel emissions logic algorithm. I decided to invent one myself as an experiment because no one in the press seems to have provided one yet.
1) Check if only the powered wheels are turning. (i.e. it's on a test rig)
2) Increase the turbo pressure
3) Allow the temperature to rise beyond the normal upper bound.
That should do it.
The car knows its on a test bed and allows the two factors most likely to burn off emissions to increase beyond their normal upper limit. It wouldn't be wise to leave them at the higher level for too long because of engine wear, but for a 20 minute test, who cares?
It's almost a surprise that more car manufacturers don't do this...Or do they?
